Purchased and added a virtual rack module & wired it within minutes. Thus I conclude it's quite intuitive. Haven't been through all the presets yet but there are some nice sounds and it's a great playground for new patch creation.

I like this app a lot. I got it when it first came out. I think the interface is very intuitive, much more so than other modular apps. You do have to know a bit about patching modules, but is a great way to practice what you have learned from other sources. The sound is very nice, perhaps not equal to some premium synths, and it has a few quirks, like the filter CV is inverted from what I’d expect, but I think it is a lot of fun, doesn’t use a lot of cpu, and of course is very flexible.
